I LOOM SHUTTLE.

SPEGIFICA'I'IQN forming part of Letters Patent No. 340,463, dated April'20, 1886.

Application filed July 11,1885.

To aZZ whom it may concern:

Be it known that I, WILTON H. SPENCER, of the city of Providence, in thecounty of Providence and State of Rhode Island, have invented a new anduseful Improvement in Loom- Shuttles, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification, in which Figure 1represents an isometrical perspective view showing the spindle inposition for use. Figs. 2 and 3 are detached perspective views showingthe spindle and the supportingframe therefor, the spindle beingrepresented .in different positions.

, spindle is expanded and caused to more cffectually hold the cop whenthe shuttle is in use, which insures a continuous even supply of theyarn while the shuttle is in motion throughout the entire unwinding ofthe cop or yarn, and whereby the spindle is securely locked in positionin the shuttle-body when depressed, as hereinafter described andclaimed.

In the accompanying drawings, A, Fig. 1, represents the body of theshuttle; B,the spindle; and C, Fig. 2, the frame in which the spin dleis made to operate. The spindle B is a split spindle-that is to say, iscomposed of two parts,joined at one end to form the point, the oppositeor heel ends being separate. It is pivoted a suitable distance from oneend of frame 0, and the tapering arms e 6, Fig. 3, of

' the heel portions are slightly bent sidewise at or near the pivot-hole and diverge laterally to their extended ends. The frame 0 isconstructed of a square form, having a bottom and two sides, of whicheach side is provided with a lip, d, at its top edge, Fig. 3, said lipsbeing turned inward and operating to bring the arms 6 e firmly togetherwhen the latter are pressed in between the lips in lowering the spindle,as shown in Fig. 2, and forming beneath them a space for the springs ora. Said springs are fitted lengthwise in frame 0, one under each of theaforesaid lips, and they are held in place by the pin a passing throughone Serial No. 171,289. (Nomotleh) of the ends of each. The spindle B isplaced between the springs or n, as shown in Fig. 2, and the frame 0 islet into the body A of the shuttle at one end to remain fixed therein,and the whole as arranged are pinned in the end by pin a, Fig. 1.

From the foregoing the nature and the 011* erationand advantages of myinvention will be plainly seen and understood to all familiar with theworking of that class of shuttles referred to. XVhen the point end ofthe spindle is elevated, as shown by dotted lines in Fig. 1, the arms ec are withdrawn from the frame 0,

as shown in Fig. 3, and the expansive sides of 6 5 the body of thespindle, from the point of the spindle rearward to the pivot-hole at a,will be permitted to come in close proximity to each other, and the copmay readily be placed in position thereon without disarranging or, as itis termed, stabbing the cop or causing waste. If the spindle is nowdepressed, the cop being on the same, the arms 6 e are brought inbetween the lips (Z (Z, pressing them rigidly together, and so holdingthem, thereby forcing the expansive sides of the spindle apartlaterally, and firmly securing the cop in place for use, Fig. 2. Thesprings n n have their free ends formed with ridges upon their innersides, and the ends of the arms 6 e are provided on their outer sideswith corresponding grooves. lVhen the spindle is depressed,as aforesaid,the ridges spring into their respective grooves, by which arrangementsaid spindle B is retained in thebod y A of the shuttle without the useof the ordinary spindle locking spring.

An advantage in my improvement, which I have demonstrated by actualexperiment, is that when the arms 6 e are passed in between the sidelips of frame 0 and are held together rigidly therein, the expandedsides of the body of the spindle are certain and uniform in their actionin holding the cop throughout the entire unwinding of the yarn.

I am aware that a solid spindle has been constructed with a split heel,the wedge-shaped portions of which have been fitted between the upwardlyconverging sides of a supportingframeintendedto be applied to ashuttle-body to hold the spindlein position when depressed, and this Ido not claim.

My improved construction not only secures I tion with the frame 0,having the lipsd d, and 10 the effective holding of the spindle in itsdethe separate springs 10 n, adapted to engage pressed position, buteffects the expanding of with the said grooved heel portions, substanthebody of the spindle. tially as specified. 5 Having thus described myinvention and its T use, what I claim is- WILTON SPEB The splitexpanding spindle B, formed with \Vitnesses: diverging heel portionsgrooved on their outer WALTER B.
